Correct Answer & Explanation
Option A
• The pattern followed is that each letter in the word is shifted one position forward in the alphabet.
• T (+1) → U
• A (+1) → B
• P (+1) → Q
• E (+1) → F
• Applying the same pattern to 'CHAIR':
• C (+1) → D
• H (+1) → I
• A (+1) → B
• I (+1) → J
• R (+1) → S
• So, 'CHAIR' is coded as 'DIBJS'.
